IMPROVEMENT IN' FERTILIZER-ATTACHMENT FOR FLOWS.

4 The Schedule referred tdin Letters Patent and making part of the same.

full, clear, and exact description thereof, reterenceheing.

had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

The nature of my invention yconsists in the con? struction and arrangement offa fertilizer-attachment for plows, which can be transferred, with very little trouble, from one plow to another.

In order to enable others skilled in the art to which my invention appel-,talus to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, in vwhich- Figure 1 vis a side view of a plow, with my attachment; and

Figure 2 is a bottom view of thehopper, containing the fertilizer.

A represents the plow-beam; B, the plow; and C, the lhandles of any plow, made in any of the known and usual ways. y v

To the side of the beam A is secured a hopper, D, directly in front of the plow. I

This hopper may be secured to the beam in any` suitable manner, so as to be easily removed, but I prefer attaching it in the following manner, namely:

A .square iron frame, a, is secured to the'bea'm A, by means of a shank that goes through the beam, and fastened by'nuts on the opposite side.' The hopper D sits in this iron frame. l

The bottom b of the hoppenLD is concave, with an opening, through which thefertilizer'is discharged, and is removable, so that others, with larger or smaller opening, may be substituted. q,

Under the bottom b is pivoted a stop-plate, d, which is held, by means of aspx-ing, c, in such `a manner as to cover the opening in the bottom, and prevent the fertilizer from passing through.

A wire, j', runs from the outer end of the stop-plate d, upto the handle C, and has a loop formed at its upper end, within'easy reach ofthe operators indexnger, so thathe can at suitable intervals, by a slight -pull on said wire, open the bottom of the hopper, and

placed a shaft, h, having arms it', which, .when the shaft is revolved, as will be hereinafter set forth, stir the fertilizer, prevent it fromclogging, and facilitate its-egress through the opening in the bottom.

IOn the under side of the beam A, a suitable distance in front of the hopper and plow, is secured a spring-bar, F, which extends downward and` toward the rear, as seen in fig. 1.

I Between the front end ofthe spring-bar F and. the

beam A, is placed a wedge, .,G, through which the bolt, that vsecures the springbar, passes, and .this

V.wedge maybe exchanged for one larger or smaller, so

as to canse the said spring-bar to incline at anyangle desired. v

Through the rear end of the spring-har F passes a shaft, having, at its outer end, a circular disk, H, with arms I I radiating from the centre, and at its vother end a pulley, J, which, by means of a belt, m, is connected with a pulley, E, on the end of the shaft h, outside-of the hopper D.

The wheel H I may, if desired, be provided with a rcircumferential rim. n When the plow is in motiou,the wheel H Lresting' on the ground, revolves, and through the belt ml communicatesmotion to the stirrer h t', inside of the hopper. v

0n that side of thebeam A, where the beltm passes, is pivoted an arm, n, provided at its rear end with a friction-roller, o, which bears against the belt m, and by this means, the belt canvat all times .be kept taut enough to revolve the stir-rer. f

This attachment can be readily transferred from one plow to another. -v

Having thus fully described my invention, What l claim as new, and desire to secure by Letters Patent, isv'1. .The hopper D, constructed as described, with removable bottom b, stop-plate d, spring e, andvwire f, all' substantially as and for the purposes herein set forth. Y

2. Securing the hopper D to the plow-beam A, by means of the iron fram'a, substantially as herein set forth.

3. The spring-bar F, provided with wheel 'E I, and pulley7 J, and connected to the plow-beam A, sub-k stantiallyin the manner and for the purposes herein set forth.

4.,.The stirrer h t', belt fm, pulleys EJ, arm n, and roller o, all constructed and arranged substantially in the manner and for the purposes herein set forth.

5.*l In combination with a plow, a fertilizer-attachment, constructed substantially as herein shown vand described. ,Y

` In testimony that I claim the foregoing, I have hereunto set my hand, this 17th day of August, 1869.
